For me its 100% scam
They should give a list of wallets adresses where the stolen crypto has gone. Some of the funds would be blocked and retrieved by exchanges and "thief" would need to find more safe places to cash out. But most of the people would be aware its stolen funds.
Except of that cryptopia staff decided to keep silence and let the funds flow annonymous. Only small part was caught and blocked by binance

I wouldnt be sutprised if all top volume coins has been cash out and only zero volume coins left intact. Maybe even they will give them back

And dont think they will reipen cryptopia. They already show how much they care about customers hiding behind polices backs and lying thats police investigation caused no updates and information
